Window Cleaning in Lake Oswego, OR
RESIDENTIAL SERVICES

Clearly Amazing cleans windows for homes and businesses in Lake Oswego, working from an office on SW 74th Avenue in Tigard. Interior and exterior glass, frames, sills, tracks and screens. Two kinds of window dominate the work here and they could hardly be less alike: small divided panes in century-old sash on the streets north of Lakewood Bay, and broad modern glass pointed at a private 405-acre lake. They need different hands.

First Addition has the oldest glass in the city
First Addition, informally Old Town, is Lake Oswego’s oldest neighborhood, laid out north of Lakewood Bay to house workers of the Oregon Iron and Steel Company in the late 1800s. Its housing runs from just before 1900 through Colonial Revival bungalows of the 1920s, with examples dated around 1925 still standing.
Two things follow for anyone cleaning the windows. The first is the glazing. Where original wood sash survives, the pane is held by a bed of hardened putty and a few glazier’s points rather than a modern gasket. Old putty gets brittle, and a sash painted over a dozen times can have very little left holding the glass at the edges. That is a reason to work by hand and to be honest about what we find, not a reason to avoid the job — these are the windows that most reward being done properly, and a divided sash takes longer than a single pane of the same area.
The second is access. Rear alleys of roughly 20 feet are a common feature of the neighborhood’s original layout, built for off-street access. In practice the back elevation of a First Addition house is often approachable from the alley on level ground, which is a safer setup than balancing a ladder in a side yard. We look at that at the estimate, because it changes how the day runs.

Lakefront glass, and how we reach it
Oswego Lake is not a public lake. It covers 405 acres and is owned and managed by the Lake Oswego Corporation, a private entity formed in 1942 when the Oregon Iron and Steel Company deeded the lakebed and rim property to it. Access runs through 20 private easements attached to particular deeded properties, with roughly 3,000 or more homes carrying deeded eligibility. There is no general public frontage to work from.
That has a straightforward consequence for window cleaning. The lake elevation is the one the house was designed to be looked through, and usually the one with the largest glass. It faces water, which throws hard reflected light at the pane and shows every streak and drip mark a north wall would hide. It is also nobody’s thoroughfare, so it never gets a passing glance from the street — people judge it entirely from the inside, which is why interior work matters as much as exterior on that side.
Reaching it is the other half. Ground falls toward the water on many of these lots, so the lake side of a two-story house can present three stories of drop, over decking or planting rather than lawn. We work from ladders and poles, set up on the property rather than on the water, and will say plainly at the estimate if a pane needs equipment we would rather not improvise on a slope.

Irrigation is worth flagging wherever you are in the city. A sprinkler head clipping a ground-floor window through a dry Lake Oswego July etches mineral deposits into the glass. Caught early it cleans off; left for several seasons it stops being a cleaning question and becomes a glass question. If you have a zone hitting the house, move it regardless of who does your windows.
When to schedule
Late May or early June is the strongest slot. The wet months are behind you, the fir and maple pollen has finished dropping onto everything, and you get the clearest glass of the year going into the season when the lake side of the house is in use every day.
Late September is the other good one, and arguably the more practical. Cleaning before the fall rain means the winter’s water runs over clean frames and clean sills instead of picking up a summer of dust and carrying it down the pane. December is the wettest month here, so the frames get a workout.
Twice a year suits most houses here. Once a year, take September. Any other month is a fine time to book — people call in November for the holidays, in February because the low winter sun has made every mark visible from the sofa, and in midsummer before photographs are taken. All good reasons, and the same clean glass at the end of it.
Questions Lake Oswego customers ask
Will cleaning damage old wood windows?
Handled properly, no. Hand work rather than aggressive scraping, no flood of water at the glazing line, and drying rather than leaving water sitting on the putty. Where a sash is already failing — soft rail, missing points, putty coming out in pieces — we show you before touching it, because that is a job for a sash restorer.
Do you need lake access to do the water side?
No. We work entirely from your property. Access to the lake itself runs through the Lake Oswego Corporation’s easement system and has nothing to do with us — every pane we clean is reached from the ground, a deck or a ladder set on your own land.
Are screens, tracks and storm windows included?
Screens and tracks, yes, as standard. Tracks matter more here than in a dry climate, because debris packed into a track holds water against the frame through the wet months, and on wood that is where rot starts. Storm windows and older removable panels vary house to house, so tell us what you have and we will price it rather than guess.
What will not come off?
A failed double-glazing seal, which is condensation trapped between the panes, and deep mineral etching from years of sprinkler contact. Neither is dirt and neither responds to cleaning. On a lake-facing wall of glass in strong light those are the flaws that get noticed, so we would rather point them out at the estimate than have you pay for a result the glass cannot give.
How long will they stay clean?
Through summer, months. Through the wet season it depends mostly on what is above the window: clean gutters and soffits, and rain stays fairly neutral on the glass. Overflowing ones, and every storm puts a new set of tracks down the pane.
